At a glance
What we observed in this category
SentinelOne and Microsoft Defender share the top visibility score at 75%, well above the category average of 14.4%, which means the top two brands capture a disproportionate share of AI-generated mentions. SentinelOne holds a composite score of 60.0 versus Microsoft Defender's 56.2, a gap driven by citation rate (25% versus 12.5%). Microsoft Defender is the biggest riser in the dataset, jumping from rank 6 to rank 2 after a 62.5-point visibility increase, making it the most significant momentum story in this category.
Huntress presents the sharpest divergence between visibility and citation in the entire dataset. It holds only 12.5% visibility but a 50% citation rate, the highest of any brand audited, suggesting AI answers reference it as a source or authority even when not describing it as a featured solution. Bitdefender sits at the opposite extreme with 25% visibility and 0% citation. Palo Alto Networks, Acronis, and Fortinet each record 0% visibility yet each still earn a 12.5% citation rate, confirming that citation and named visibility operate independently here.
Google AI Mode is the top engine for every single brand in this dataset without exception, indicating the audit is effectively Google AI Mode-centric. Among the top cited external sources, Gartner and G2 appear alongside YouTube, Reddit, and Huntress's own domain, suggesting the AI anchors on a mixture of analyst review platforms, community discussion, and vendor content. The presence of ngcloudsecurity.com and cynet.com in the top cited sources points to niche security publishers carrying meaningful weight in AI citation behaviour for this category.

How to read this AEO ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
AEO rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 90 days and refresh this page automatically. How AI search ranking works →
